20 Really?

I invited Jaykob to the diner that I work at. He acted so weird. He would dart his eyes every which way almost every 2 minutes. He seemed... paranoid. But why? He asked me if the diner was always so busy like this. I looked around and but Jaykob and I were the only ones there. I looked at him in confusion. He asks,"So you can't see them?" He points to the corner that no one goes to because people say they hear voices and see things that no one can explain. When I answered,"No?" he just looked at me and said,"So you really can't see her?" and again he points to the corner. So we closed the diner and went to my house to sketch what he saw. While I was driving out of the parking lot, something caught my atttention. In the corner of my eye, I saw a black figure standing almost 7 feet from my dads truck. But when I looked, it was gone. I looked at Jaykob. He look terrified, but his look wasn't towards me, it was in the rear view mirror. I immediately looked. What I saw was jaw dropping.
